HSM10 Hough to Winterbottom

Hough to Whalley’s Green

The route section between Hough and Winterbottom would be 29.9km long. The section of route connecting to Hough from the south would be HSM08 from Madeley. The design speed would be 400kph (248mph).

The HS2 route would run on the east side of the WCML between Hough and Crewe. During construction stabilisation of and support to the WCML would be required.

Casey Lane would be realigned for 400m on the west side of the route to avoid crossing it. Weston Lane would be realigned onto a bridge over the route and the WCML. The A500 would be realigned onto a bridge to cross the route and the WCML.

The route would descend from Hough in a retained cutting to a tunnel portal to the immediately south of the existing depot. The twin bore tunnel under Crewe would be 4.65km long. Ventilation, intervention and evacuation shafts would be positioned according to the HS2 Technical Specification and Strategies.

The northern tunnel portal would be 400m south of Parkers Road bridge. The route would rise from the portal in a retained cutting. Parkers Road would cross over the route and the WCML on a bridge. The route would reach ground level to the east of Spring Farm.

From the tunnel portal the route would run within 50m of the WCML for almost 4km before bearing slightly east. The route would be within 1m of ground level for 6km. The route would pass through the route of overhead power lines. The remaining 21.5km of this route section would be over an area of mudstone with soluble deposits with active and historic salt mines (risk of subsidence).

Whalley’s Green to Higher Shurlach

The A530 (Nantwich Road) would be realigned onto a bridge over the route and the WCML. Clive Green Lane would also be realigned onto a bridge over the route.

The route would then rise on embankment to cross over the Shropshire Union Canal at a height of 6m before descending into a 1.3 km long cutting up to 11m deep. The A54 would be realigned to the west of the route to a new roundabout at the A533. The A533 would cross over the route. The route would then pass onto a 745m long viaduct to cross the River Dane flood plain and the Trent and Mersey Canal at a maximum height of 10m.

The route would then run in a shallow cutting (up to 5m deep) for 900m through an active landfill site before crossing the Puddinglake Brook flood plain on a 120m long viaduct at a height of 9m. A section of embankment (up to 9m high) follows with the route crossing over the Sandbach to Northwich railway. Whatcroft Lane would be diverted for 450m on the west side of the route to avoid it and to tie in to the A530. The route would pass over the A530.

For the next 3km the route would be on embankment (with a maximum height of 7m), crossing the Gad Brook flood plain on a 150m viaduct at a height of 6m. Crowder’s Lane would be realigned onto a bridge over the route. The route would pass through the route of overhead power lines. The B5082 would be realigned onto a bridge over the route.

Higher Shurlach to Winterbottom

Birches Lane would be realigned onto a bridge over the route. The route would cross the Wade Brook flood plain on an 185m long viaduct with a maximum height of 14m. It would continue on embankment (maximum height of 12m) for a further 3.5km crossing over the Altrincham to Chester railway, the A556, and the A559. Peover Eye and Smoker Brook flood plains would be crossed on a 185m long viaduct at a height of 18m. The route would cross over Linnards Lane (which would be realigned), followed by two crossings of a flood plain on viaducts 65m and 440m long at heights of 8m and 3m respectively.

Where the route passes into a shallow cutting (up to 4m deep), the B5391 (Pickmere Lane) would be realigned onto a bridge over the alignment. School Lane would be diverted for 350m on the west side of the route to avoid.

The route would rise onto a low embankment (maximum height 5m), crossing the Arley Brook flood plain on a 70m long viaduct at a height of 5m. Budworth Road would be realigned onto a bridge over the route. The embankment height would increase to 8m to allow the route to pass over the M6.

At Winterbottom the route would continue along section HSM12 to Warburton and HSM28A to Ardwick (and then to Manchester Piccadilly).
